I have a AT&T galaxy note 2 SGH-I317 upon which I recently installed the latest available nightly CM rom (10.2), which only gives me to Android 4.3.1.
I was wondering if its ok to upgrade the phone using a more recent rom for a different phone from the CM website, ie CM 11 for the Galaxy Note II (GSM LTE), keeping in mind that I do NOT need any radio functionality (I only use the phone in airplane mode and connect to a freedompop hotspot).
If this isn't possible, I did find a custom CM rom with CM11/4.4 on the web, but I'm unsure how this differs from my current CM setup, ie. will I still have options to upgrade my phone via the regular OTA CM updates if I am running this custom ROM? Are there any other issues I should be aware of with custom CM roms?
Also, since CM hasn't upgraded my phone since April, what are the chances they will be any updates at all for the SGH-I317 in the near future?
I've searched the threads/web extensively on both topics but I am still unclear on the ramifications, so any help is much appreciated.
